(JAVA) 자바 날짜 및 요일, 시간 제공 클래스 간단히 끝내버리기~

//캘린더를 이용한 날짜 및 시간
Calendar rightNow = Calendar.getInstance();
int year = rightNow.get(Calendar.YEAR);
int month = rightNow.get(Calendar.MONTH)+1;
int day = rightNow.get(Calendar.DAY_OF_MONTH);
int week = rightNow.get(Calendar.DAY_OF_WEEK);
int hour = rightNow.get(Calendar.HOUR);
int minute = rightNow.get(Calendar.MINUTE);
int second = rightNow.get(Calendar.SECOND);

//LocalDate와 LocalTime을 이용한 날짜 및 시간
LocalDate localdate= LocalDate.now();
int year = localdate.getYear();
int month = localdate.getMonthValue();
int day = localdate.getDayOfYear();

LocalTime localtime = LocalTime.now();
int hour = localtime.getHour();
int minute = localtime.getMinute();
int second = localtime.getSecond();
int nano = localtime.getNano();


//데이터를 이용한 날짜 및 시간
Date date = new Date();
System.out.println(date);    // Wed Nov 23 04:29:24 KST 2016 이런식으로 출력됩니다.
int year = date.getYear()+1990;                 
int month = date.getMonth();
int day = date.getDate();
int hours = date.getHours();
int minutes = date.getMinutes();
int seconds = date.getSeconds();
